Background technology
Solar cell industry development in recent years is swift and violent, and along with the continuous reduction of cost, solar cell just progressively enters among people's life, plays a greater and greater role.Thin-film solar cells is a kind of in solar cell, it only adopts the thin-film material of hundreds of nano thickness to realize photoelectric conversion, main feature is: material usage is few, be convenient in deposition on glass, can produce translucent effect, low light level power generation performance is good, the high temperature power generation performance is good, the comprehensive electric generating ability is strong etc.
Current thin-film solar cells is divided into again silicon-based film solar cells, cadmium telluride diaphragm solar battery and copper-indium-galliun-selenium film solar cell, and their main distinction is that the photoelectric conversion layer material therefor of core is different.But the basic structure of battery all adopts identical sandwich structure, and namely anterior the centre is the photoelectric conversion thin layer of core take the layer of transparent conductive film as front electrode, and the rear portion is the back electrode thin layer that conductive metallic material or its composite material consist of.
